' Tool?! it may concern 7 Be it known that via-THOMAS C. BELDING and JOSEPH J. Zmsmn, citizens. of the United States, residing at Canton, in the county of Stark and State of Ohio, have I jointly invented certain new and useful Improvements in Ridge-Roll-Forming Dies; and we do hereby declare that the following is a full, clear, and exactdesc-ription of the same, reference being had to the accompanying drawings, making a part of this specification, andto the numerals and figures of reference marked thereon, in which---v Figure 1 is a perspective view, showing the die-jaws open and the pressure-bar ele- .vated and illustrating thebifurcated bar out of engagement with the die-jaw operating or opening fingers. Fig. 2 is a transverse section 'showing the die-jaws open, the pressure-bar'elevated and a sheet of metal placed in position to be, formed or pressed into a ridge roll. Fig. 3 is a transverse 'section of the parts shown in Fig. 2 showing the pressure-bar lowered and the die-jaws closed and illustrating a ridgeroll prop.- erly formed. Fig. 4 is a section on line AYA Fig. 2. Fig. 5 is a transverse section,

and the flange forming dies located upon the die-jaws. Fig. 8 is a-view showing a portion of a finished ridge roll as formed bythe die-jaws and dies illustrated in Fig. 7.

'. The present invention has relation to ridge roll forming dies and it consists in the novel arrangement hereinafter described and morepartic ularlypointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawings, '1 reprecents the base, which is suppoited upon the bed-plate 2, which bed-plate constitutes-a part of'anywe'll known press, such as cominonly used in pressing or forming sheet metal. The base 1 is provided with the parallel beads or rolls 3, which beads" orrolls are preferably formed of T a lengthto: -correspond with the length of the. die-jaws 4, said die-jaws being provided upon their bottom or undersides with grooves 5 adapted to receive the beads or rolls 3, wherebya hinge or joint is produced, as .between the base 1 and'the die-jaws 4. Each of the diejaws 4 are provided with what might be termed teeth or fingers 6, which teeth or fingers interlace as best illustrated in Fig. 1 and are so interlaced for the purpose of producing a continuous and unbroken support for the sheet of metal designed to be oper ated upon at the initial bend of the sheet. Directly above the die-jaws 4 is located-the pressure-bar proper, which pressure-bar is provided with the head or roll 7 at its lower edge and the integral web 8, is provided with *the lateral flanges 9 in which lateral flanges are cut or formed the open grooves 10. The 'web'8 is continued a distance above the flanges 9 and is provided with an integral connecting bar 11, which integralconnecting bar is connected in the usual manner to a reciprocating bar such as 12 shown in Fig.-

invention, except that they must necessarily be present to-constitute a working machine.

To the base 1 is attached the stop 13, which stop extends upward through the recess 14 formed in what might be termed the rear die-jaw. In the drawing we have illustrated but a single stop 13, but it will be understood thatstops 13 should be located at intervals so as to bring the sheets designed to be operated upon inproper al-inement with the die-jaws and the pressurebar.

In operation the die-jaws 4 are brought into the positions illustrated in Figs. 1, 2

and 5, at which time the pressure-bar proper form the tops of the die-jaws 4. When the parts are in, the positionsv just above described a sheet or sheets of metal are placed upon the tops ofthe die-jaws, after which a downward movement is given" to the wer her Pr pe w h wn d m r is elevated so as to spaces'aid pressure-bar ment brings the lower surface of the bead or roll 7 into contact with the uppersurface of the sheet and by a continuous downward movement of the said pressure-bar a rocking or oscillating movement is imparted to the die-jaws 4, said downward movement of the I pressure-bar being continueduntil the dieof the plunger proper the die-jaws will be.

" parted or oscillated and when the pressure bar has reached its full height the die-jaws will assume the positions illustrated in Figs. 1, 2 and 5. i

To'oneend of the pressure-bar proper carryingthe integral head or roll 7 is attached the bifurcated bar 15, the bottom or lower end of which bifurcated bar is provided with the bolt 16, which bolt is for the purpose hereinafter-described. To the diebars 4 are attached the plates 17, which plates are provided with the integral curved fingers 18, which curved fingers are located over the bolt 16-so that an upward movement of the pressure-bar carrying the bifurcated bar 16 will impart a positive opening movement to the die-jaws 1'. It will be understood that the'movement of the bifurcated bar 15 and the pressure-bar proper should 'be so timed that when the extreme upward movement of the pressurebar has been reached the die-jaws will have been fully opened and in such positions with respect to each other that sheets of metal can be placed in position to be formed into ridge rolls by the downward movement of the pressure-bar and the. closing movement of the die-jaws. In some instances it may be desirable to form ridge rolls with two bends such as 19 and 20 and in other instances it may be desirable to have but a single bend such as 21, and" in order to provide for forming ridge rolls of the two styles shown in Figs. 6 and 8 the die, or what might be termed bend or flange forming dies 22a're provided which are con nected to the pressure-bar proper or to 'the die-jaws 4,'reference being had to the particular style of ridge roll designed to be formed. The flange forming dies '22 when connected" to the pressure bar as illustrated in Figs. 2 and 3 form or produce a single bend in the sheets operated upon as illustrated in Fig. 3 and in the finished product Fig. 6. lVhen two bends such as 19 and 20 are desired whereby the ridge roll connecting flanges 23 are produced the die-bars 22.

are transposed, or in other words removed from the pressure-bar and connected to the die-jaws as illustrated in Figs. 5 and 7.

In order toprovide means for rapidly and. without inconvenience placing the replaced from time to time.

noaaose sheets of metal into position to be operated 'but owing to the fact that said apron is held against any sliding or reciprocating movement by the bar 25 that as the die-jaw 4 located directly under the apron or plate 24-. is rocked or oscillated, said apron' willbe moved or swung upward as indicated in dotted lines Fig. 5, which upward swinging movement withdraws said apron from under the sheets and into such a position that it does not interfere in anyway with the formation of the ridge roll during the time the ridge roll is being formed. M

It is well understood that, in the pressing of metal more or less spring action takes" place after the metal has been fprmed owing to the strain brought upon the metal during its formation and in order that the ridge rolls may when finished have straight diverging parts such as 27 between the bends 28 and 19 or 21 the working ,faces of the die-jaws 4 are slightly convexed by which arrangement the metal operated upon is slightly bowed or brought into convexo-concavo form, but when the sheets are released from their greatest strained position they will assume the form shown in the finished product, Figs. 6 and 8.

For the purpose of preventing any end movement of the die-jaws the base.1 is provided with't-he plate 29 which plate prevents end movement in one direction and the bifurcated bar 15 assists in holding the die-' jaws from end movement in either direction,

but we donot desire to be confined to any specific device or devices for holding the diejaws against end movement as many ways may be provided without departing from the nature of our invention; 1

It is well understood thatmore orless wear will take place from long and continued use during the time. the ridge rolls are being formed and especially as between the edges of the sheets and the parts coming in contact therewith and in order to provide against this wear at little ex ense the die-jaws t are provided with the wear plates 30, which wear plates are-connected to the die-jaws by means of suitable rivets or their equivalents 31, which wear plates can be It will be understood that the die-jaws 4 should be provided with grooves 31, which grooves are so located that when the diejaws are brought into their clamping positions the surfaces of the grooves 3l 'will be ters Patent, is'- notc es so positioned that the sheets of metal will be.

clamped or pressed between the surfaces of the grooves 31 and the surface of the head or roll 7, so that a roll is formed upon the finished product.

. For the purpose of providing contact points as between the sheets and the pressure-- and shapes of die-jaws and pressure-bars can be substituted for the ones shown in the drawings.

In some instances it may be desirable to turn the apron 24 down and into the position shown in Fig. l and this is more especially true when the flange forming'dies 22 are located upon the pressure-bar proper.

It will be understood that the apron 24 should be provided with the angled flange 24:,wh-ich angled flange serves the purpose of lifting and guiding the sheets as they are placed in the position to be acted upon.
